Multicam Issues, serious problems

First make sure that you have covered the basics. It looks like you have Angle Assembly taken care of. Make sure that for Angle Clip Ordering, you have selected Content Created. Angle Synchronization should be Automatic and the box for Use audio for synchronization is checked.

It looks like your two biggest problems are clip length and audio quality. If each camera has 20+ clips (each less than a minute) and the audio is as noisy and indistinct as I imagine yours is (it looks like a drag race), then there isn't much for the software to work with. Honestly I would just try to sync everything by hand.

Next time, let the cameras run longer. At the very least, every time you press record try to roll for about two minutes. It also wouldn't hurt to record a hand clap or something distinctive. Ideally you should just roll the cameras through the entire event. If that is not feasible, then pick certain blocks of time to run for longer.
